Avocet -- Pembroke

The Avocet was seen again yesterday, & is likely to have have been on the river since 17 Feb.
The bird seems to favour an up-river area off Monkton, where there is no access.
The bird may be viewable from the Pennar side, access from Ferry Road, the road that leads to the foreshore that is nearest to Pembroke.
No real idea what state of tide is best, the Avocet wasn't seen today at high tide. But 1 Black-tailed Godwit, 3 Greenshank the highlights of small groups of roosting waders.
Also 1 BH Gull, a winter adult but with the only dark pigmentation on it's head, a small red bill. Otherwise all plumage.....white. It's structure / size too black-headed to be a hybrid?
